To all whom it may concern:

Be it known that I, GUY L. HAMMOND, a citizen of the United States, residing at Bridgeport, in the county of Fairfieldv and State of Connecticut, have invented. a certain new and useful Improvement in Aline ment Mechanism for Line-Casting Machines, of which the following is a full, clear, and exact description. I Q '7 This is an improvement in machines which cast line long type slugs from assembled lines of matrices; and the object of this invention is toefiect vertical alinement of the assembled matrices lmmediately prior to their presentation to the mold.

The invention is shown as embodied in a machine in which the assembled matrix line is supported for presentation to the mold on thesame elevator which subsequently carries delivers them to the matrix distributing mechanism. 1 V I The .invention iconsists in the provision above the matrix line; of an overhanging surfacefwhich occupies a definite relation to the mold slot and which is adapted to be engaged byalinement surfaces on the matrices, and *the employment of novel means bywhich, just prior to the all of the matrices are pushed up so as to bring the vided into engagement with the alinement surface above them.

W In the drawing, Figure 1 is a rear elevation of an elevator and associated mechanism embodying the invention the matrix line on said elevator being sectioned, and parts; of; the elevatorbeing broken. away. Fig. 2 is a side elevation of the elevator and asectional view of some associatedparts; andFig. 3 is a sectional side elevation, of the part of the elevator by which the matrix line is supported and alined'.

. Beferringtothe parts by letters, repre sents the elevator which is to be moved vertically up and down by suitable means and is guided by suitable means,;asfor example, by two vertical guide rodsF and F. The elevator is provided with amatrix supporting shelf e,.which when the elevator is down, is in such position that aline' of matrices maybe pushed on o the same. During the casting operation, the matrix line is compressed laterally between a fixed abutment A recess in the elevator V zontal pins to one end of the C. This much of which is located adjacent elevator and an end clamp the construction is old.

The shelf '6 has a slot 6 from its top and running from end to end. Tn-this/slo't is an alining bar D which proects above the top surface of the shelf, this pro ecting part being in the form of a dovetalled rib d which enters the dovetailed notches m in the bottom of the matrices M. This particular dovetailed shape of the alining bar rib has a useful function in the machine, but is not essential to the particular invention which the appended claims define. This bar hastwo (more or less) inclined surfaces d 0Z ,'on its lower edge, and these are for engagement with similar surfaces g 9 on thetop of the slide G. This slide is located below the alining bar and in the same shelf. This slide is movable endwise but the alining bar is not, being held a ainst such movement by horifixed to the elevator shelf and going through short vertical slots (5 in the alining bar. The alining bar is moved down against the slide G by the action of a spring extending down J which is connected with the alining bar at its upper end, and, passing through a hole in the sllde, is connected at its lower end the with a horizontal pin j which engages bottom of the elevator shelf.

A stud K projects horizontally forward from the slide G through a horizontal slot in the elevator. Thisstud will be in such position that when the elevator descends, it will pass between the forked ends of an arm N, which is rigidly connected with another arm N? so as to form in effect a lever which is fulcrumed at n. This arm N engages with a rotatable CamP and is held in such 7 engagement by a spring S. When this cam in rotating reaches a position suchthat the arm-N can drop into the depressed part of the cam, the spring S will so move the forked arm N, that it will move the slide G to the right, as shown in the drawing, and thereby through the action of the inclines g g ,,d ,.d on it andon the alining bar D referred to, will cause such alining bar to move up. In this upward movement, the upperedge of the alining bar will engage the matrices and push them up untiltheir top edgeswhich serve as alining surfaces engage the overhanging alinement flange 0 of g matricesand has a 7 top surface, a 'horlzontal alming bar which.

the elevator.

matrices with the pot nozzle rest in adefinite these parts. Vhen the elevator is lowered,

This accurately alines the respect to the mold IV and it rests upon carefully adjusted supports T;
